bug#49648: 28.0.50; Installing a package: Garbage in the popup

Severity: minor

From emacs -Q:

1) M-x list-packages
2) select any package (in my case: eglot)
3) click "install"

The popup "Install package eglot-1.7" has garbage characters before
"eglot" and after "1.7".  Screenshot attached.

Package installation works, so this is just a minor optical flaw.

Emacs didn't crash.

Emacs has been built from the repository with "make bootstrap" on Debian
buster.

Looks like some encoding problem: those garbled characters are
supposed to be curly quotes.  That's what I see here.  Maybe this is
specific to the Lucid builds?

Does anyone else see this problem?

I'm unable to reproduce this under Debian/bullseye:

Your screenshot looked like it was displaying the pop-up using the wrong
coding system.  I didn't see anything immediately suspicious in your
environment from the bug report: "value of $LANG: en_US.UTF-8".  Which is
the same as I have.

Anybody else know what could be causing this?

Maybe your font misses curly quotes code points.

From your screenshot the font appears to be the default (bitmap?) Xorg
font. Fontconfig usually fallbacks to such fonts as a last resort, if it
couldn't find anything better on request by emacs.

So maybe just install better fonts and then tweak fontconfig (if it
doesn't pick up them automatically).

No, it isn't a font issue: you clearly see 3 "characters" instead of
just one.  So Emacs tries to display the UTF-8 byte sequence, treating
each byte as a character.  Missing font glyphs cannot cause that.

I tried a

./configure --with-x-toolkit=lucid

build, but I still can't reproduce the problem.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Nobody else was able to reproduce this problem, apparently.  Do you
still see this in recent Emacs/OS versions?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
